AuntieBS is not a neuroscientist, so to flat-out declare this to be bullshit is out of her league.  But, such “studies” should be viewed with a jaundiced eye, because there is so much negative pressure against cannabis from Big Pharma, so see its use as reducing their profits.

When you read reports of modern cannabis strains being more potent, be wary.  Instead of smoking entire joints, the modern cannabis user enjoys just a toke or two, akin to a shot or two of vodka vs a six pack of beer.  The cannabis ingestion level may be the same, but the tars and combustion byproducts is much less with stronger strains.  Having said that, there are no details as to the amount of cannabis given to the test mice, and how that would extrapolate to human use.  If a human got as wasted as they could possibly be and remain awake, there may not be much remembered.  But, the amount of intoxication under “normal” use, is much less and long-term memory is not affected.

So, I question the veracity of this assertion and remain unconvinced, though I cannot discount it 100%.  As with most things, moderation is a good concept.

In a study looking at brain scans of people with mild loss of thought and memory ability, researchers report evidence of lower levels of the serotonin transporter — a natural brain chemical that regulates mood, sleep and appetite.

A lay person, or a person intending to mislead, would jump to the conclusion that low serotonin levels cause dementia.  We constantly see that when article such as “Cannabis users have lower IQs” and “Teens who use cannabis less likely to succeed in life”, and other such nonsense.

I am happy to present this good quality example from Johns Hopkins by the simple phrase: “Previous studies from Johns Hopkins and other centers have shown that people with Alzheimer’s disease and severe cognitive decline have severe loss of serotonin neurons, but the studies did not show whether those reductions were a cause or effect of the disease. Results of the new study of people with very early signs of memory decline, the researchers say, suggest that lower serotonin transporters may be drivers of the disease rather than a byproduct.”

True, they may believe that the reductions are causal, based on other studies, but they do NOT jump to conclusions like so many biased cannabis reports that strike sour notes with me.   I wish more researchers were wiser and more forthcoming when finding correlations, when causality has not been established, instead of foisting propaganda and lies.

Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

The DEA must be upset.  Clearly, they ignore all the scientific evidence and pursue their own job-preserving ways, while they ruin people’s lives and stifle research.  And, Congress knows this (or are complete idiots) but has their lips firmly on Big Parma’s butt cheeks.  (Sigh)  When will we ever emerge from the dark ages?
